adding fallback for error (#66)

* adding fallback for error

* fixing test cases

* fixing test cases

* increasing timeout

* bumping up version

* adding support for card_brand

* add card brand simulation test with proper error handling

* fix flaky test_list_entities - handle eventual consistency

* Adding check for test case

* fix test_list_entities to handle eventual consistency in entity indexing

* fix test_list_entities - use retrieve instead of get
